HEATING TIRES.

SPECIFICATION forming part of Letters Patent No. 426,741, dated April29, 1890. Application filed January 7, 1890. Serial No. 336,142. (Nomodel.) i

To all whom it may concern:

Be it known that I, LUTHER SIMMONS, of Buckner, in the county of Jacksonand State of Missouri, have invented a new and Improved Apparatus forHeating Tires, of which the following is a full, clear, and exactdescription.

My invention relates to an improved device for heating Wheel-tirespreparatory to setting them on the wheels.

Heretofore the usual method for heating tires has been to place them ina tier on or near the ground in the open air andbuild a wood fire aroundthe same. This plan is wasteful of fuel and takes time to properlyeffect the even heating of one or more tires.

The object of my invention is to produce a simple compact portableapparatus which can be employed to utilize the heat of an ordinarysmiths forge, whereby one or more tires can be speedily and evenlyheated and the operation be inspected as it progresses.

To this end my invention consists in certain features of constructionand combinations of 1 parts, as is hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in both the figures.

Figure 1 is a partly-sectional side elevation of the apparatus inposition to receive the products of combustion from aforge-fire, onedoor of the tire-receiving chamber being open and partially broken away;and Fig. 2 is a plan view of the device partly broken away and removedfrom the forge-fire.

A represents the tire receiving and holding chamber, and consists of twoconcentric rings or walls a CL, that are held spaced apart by sideplates Z) thereto attached, and these rings, being of equal width, areadapted to form tight joints on their free edges with the doors 0 c,which are hinged at d to the outer wall a of the annular chamber A. Asit is essential that the door-joints should all be tight, their edgesare made to impinge against each other when closed, and an overlappingjoint-piece e is formed on or secured to the door 0, as shown in Fig. 2.

At f a conical nozzle is laterally projected from the outer wall a ofthe chamber A, upon which is fitted the flaring end of a horizontal pipeB, which is enlarged to produce a capacious throat-piece at f, that islocated over a coal fire on the ordinary smiths forge 0, as shown inFig. 1.

The throat-piece f is located in close proximity to the fire on theforge 0, which fire may be raised some from the top surface of theforge-bed, so that the force of the blast which intensifies combustionof the coal or coke used I for the fire will drive a strong current ofhot gases of combustion and rarefied air into the pipe B, and thenceinto the tire-heating chamber A. It is feasible to use the fire of theforge for light work while the tire'is being heated, it being intendedthat the front of the forge be left unobstructed and the heating devicelocated at one side or at the rear of the forge bed 0, so as to permitfree access to the fire.

A discharging-thimble g is placed near to the inlet-nozzle f, but not inline with it. Said thimble g projects upwardly and is in connection withthe bent end of a waste-pipe D, that is of sufficient length to conveythe waste heat and gases into the hood-E, which is the usual meansprovided to transfer the waste products of combustion thrown off fromthe forge-fire to an upright draft-flue.

The chamber A is furnished with wheels h, whereon it rests, and maybetransported from one locality to another. WVhile two doors arepreferably used to close the open side of the chamber A, one door willanswer the purpose, and other means may be adopted to adjust the door ordoors in place and dispense with hinges; hence I do not limit the scopeof my claims to the employment of these adjunctive features, althoughthey are preferred as convenient and facilitate the operation.

In putting the apparatus into senvice there is a good fresh fire startedin the forge by fanblast or the ordinary bellows, (not shown,) and thechamber-Awheeled into position near the forge, so that the pipes B and Dmaybe properly located. The tire to be heated is now placed in thechamber A and the doors 0 0 closed and secured by a latch-piece 0*.(Shown in Fig. 2.) Bothof the pipes .BD are now attached to the chamberA and the air-blast started, which will create an intense fire, the heatfrom which will traverse the pipe B in the direction indicated by thearrows therein and pass around the tire located in the chamber, heatingthe same evenly, the doors 0 c affording access to the interior forinspection of the work as it progresses. After the heated products ofcombustion have circulated from the point of inlet at the nozzle f tothe dis charge-thimble g they are transmitted to the flue of the forge,as previouslyindicated. As the discharge-nozzle g is out of line or atthe side of the inlet f, the current of hot gases will be driven forwardinto the chamber A,\vhieh is sealed by its doors 0 0', making thecircuit of said chamber before discharge, the natural draft of thechimney of the forge, of which the hood E is the lower portion, causinthe escape-pipe D to remove the hot prolation of hot. air around it anda means to seal the open side of said chamber, of an inlet for heat, anescape-orifice for Waste heat, and a heat-supply from a forge-fire,substantially as set forth.

2. The combination, with an annular chamber having four Wheels andadapted to be opened and sealed, of a heat-induction pipe and awaste-pipe for heat, so connected that the heat will traverse thechamber before it is discharged, and a forge-fire which is closelyconnected to the heat-induction pipe, sub stantially as set forth.

3. The combination, with an annular chamber, four revolublc Wheels atits base for transportation of the chamber, having an adjustable doorand an inlet and an outlet for heat an induction-pipe for heat, and aWaste-pipe adapted to remove the heat after the same has traversed theannular chamber, of a forge-fire which furnishes heat for the chambers Aunder blastpressu re and may be employed to heat metal also,sul'istantially as set forth.
